KQ-SVD: Compressing the KV Cache with Provable Guarantees on Attention Fidelity
Damien Lesens, Beheshteh T. Rakhshan, Guillaume Rabusseau
The Key-Value (KV) cache is central to the efficiency of transformer-based large language models (LLMs), storing previously computed vectors to accelerate inference. Yet, as sequen…
